[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] Reference Figures 1 to 3To achieve the above objectives, this utility model proposes a highly waterproof digital display screen, comprising a screen body, an upper cover 1 connected to the upper end of the screen body, and a lower housing 2 connected to the lower end of the screen body, the upper cover 1 and the lower housing 2 encapsulating the screen body internally; the bottom of the upper cover 1 is provided with a flexible sealing part 11, the upper cover 1 and the flexible sealing part 11 are similar rectangles, and the periphery of the upper cover 1 facing the flexible sealing part 11 is provided with a plurality of locking holes 12, the locking holes 12 passing through the flexible sealing part 11; the inner wall of the top of the lower housing 2 is provided with a connecting groove 21, the flexible sealing part 11 abuts against the connecting groove 21, the connecting groove 21 is provided with a plurality of mating holes 22 corresponding to the locking holes 12, the width of the connecting groove 21 is smaller than the width of the flexible sealing part 11, the upper cover 1 and the lower housing 2 enclose and form an installation space for accommodating the screen body; when the screen body is in the installation space, the flexible sealing part 11 covers the outer periphery of the screen body.

[0028] The structure of the upper cover 1 and the lower shell 2 can make the external waterproof structure of the entire digital display screen easy to maintain while sealing and waterproofing it;

[0029] The connecting groove 21 at the bottom of the upper cover 1 facing the lower housing 2 is provided with a flexible sealing part 11. The flexible sealing part 11 can be made of flexible, elastic, waterproof and insulating materials such as rubber, silicone, and plastic, which have good deformation ability. The upper cover 1 itself is made of a relatively hard material. The locking hole 12 is opened in the upper cover 1 and passes through the flexible sealing part 11. The upper cover 1 can limit the bolts that pass through it, so as to prevent them from being difficult to align with the mating hole 22. With the help of the upper cover 1, the locking hole 12, the mating hole 22, and the connecting groove 21, the installation and disassembly between the upper cover 1 and the lower housing 2 can be easily completed, making the whole structure easy to install.

[0030] The flexible sealing part 11 has good flexibility. After the bolt force is applied to the upper cover 1, the upper cover 1 will continuously squeeze the flexible sealing part 11, causing it to abut against the connecting groove 21 and deform, and completely fill the entire connecting groove 21. The entire structure has good waterproof sealing performance. Moreover, as the flexible sealing part 11 deforms, it will wrap around the outer periphery of the entire screen body, making the installation of the screen body more stable and preventing it from shaking, colliding, etc., which would damage the digital display screen itself. After the flexible sealing part 11 fixes the screen body, it has good shock absorption capability and can better protect the screen body.

[0031] See also Figures 1 to 3 In one embodiment of this application, the bottom surface of the lower housing 2 facing the upper cover 1 is provided with a receiving groove 23 for mounting the screen body, and the width of the receiving groove 23 is greater than the width of the inner wall of the flexible sealing part 11.

[0032] By setting the receiving groove 23, the screen body can be placed into it first during the installation process and initially fixed by the receiving groove 23. This makes it easier for the flexible sealing part 11 to completely lock the screen body through deformation after the upper cover 1 is sealed on the lower shell 2, thereby improving the protection effect.

[0033] See also Figure 2 In one embodiment of this application, the receiving groove 23 is provided with a sealing connection part 3 facing the screen body, and the sealing connection part 3 is wrapped around the pin of the screen body.

[0034] The sealing connection part 3 is also made of flexible material, and has a groove on it for the pins of the screen body to pass through. By setting the sealing connection part 3, the pins of the screen body can be well protected, and water can be prevented from entering the screen body from the pins and causing damage when the digital display screen encounters unexpected situations during transportation. This can effectively improve the waterproof performance of the digital display screen.

[0035] See also Figure 2 In one embodiment of this application, the sealing connection part 3 and the receiving groove 23 are arranged along the central axis, and the bottom wall of the lower housing 2 is provided with a relief groove 31 facing the sealing connection part 3, and the relief groove 31 surrounds all the pins of the screen body.

[0036] By setting the relief groove 31, the sealing connection part 3 has a certain deformation space after deformation, which prevents the bottom of the lower housing 2 from being lifted after the sealing connection part 3 is deformed, thus hindering the installation of the digital display screen. All the pins are in the relief groove 31, which makes the installation efficiency of the entire display screen higher.

[0037] See also Figure 2 In one embodiment of this application, the sealing connection portion 3 is provided with a covering structure 4 facing the pins of the screen body. The covering structure 4 is hemispherical, and the outer periphery of the covering structure 4 is connected to the screen body. The pins of the screen body pass through the arc apex of the covering structure 4.

[0038] The pins are covered by a hemispherical covering structure 4, with the pins passing through the apex of the arc. The hemispherical structure allows the retraction force of the covering structure 4 to better cover the pins, thereby improving the waterproof capability of the entire lower housing 2.

[0039] See also Figures 1 to 3 In one embodiment of this application, a sealing strip 13 extends from the outer periphery of the upper cover 1 in a direction away from the flexible sealing part 11. The sealing strip 13 abuts against the lower housing 2, and the sealing strip 13, the lower housing 2, and the flexible sealing part 11 enclose to form a sealing structure.

[0040] The connecting groove 21 is opened on the inner side of the top of the lower housing 2. When the upper housing 1 is in the closed state, the sealing strip 13 extending from the outer periphery of the upper cover 1 will abut against the outer periphery of the lower housing 2 to form a preliminary seal. At the same time, the preliminary sealing structure can work with the flexible sealing part 11 to form a more tight sealing structure. Furthermore, the preliminary sealing structure can cause the flexible sealing part 11 to deform in the direction away from the sealing strip 13 so as to cover the outer periphery of the screen body, thereby efficiently fixing the screen body. The sealing structure can further improve the waterproof capability of the digital display screen.

[0041] See also Figures 1 to 3 In one embodiment of this application, the upper cover 1 is provided with a light-transmitting part 14 facing the screen body, and the light-transmitting part 14 is provided with a light-transmitting unit 15 corresponding to each display unit of the screen body along the direction away from the screen body.

[0042] Digital displays typically have multiple display units, each displaying different information such as time, temperature, and operating status. To ensure optimal operation, different display units generally emit different colors of light. To further enhance the display effect, a light-transmitting section 14 made of transparent material is provided in the center of the top cover 1. To improve the light transmission effect of the light-transmitting section 14, independent light-transmitting units 15 are provided on the light-transmitting section 14 corresponding to different display units of the digital display. The light-transmitting units 15 allow for better light dispersion. The independent light-transmitting units 15 prevent interference caused by differences in the color and intensity of light from different display units, thus independently dispersing the light of one display unit. This structure improves the light emission effect of the digital display and enhances the user experience.
